Being in the water only relieves discomfort while I'm in the water. I also did a lot of water therapy post op for my first knee as flexion was an issue...again, I could bend the knee much easier in the water, but it made no difference when out of the water. I am seeing a neurologist later this month. I'm taking Gabapentin which may be helping slightly. I find I can't take it twice a day as it makes me too sleepy during the day.
